MC 927138 - Independent Inspection Effort No items of noncompliance noted.
The inspection results were attained through direct observation and discussions with licensee personnel.
The inspectors conducted a walk-throug~n inspection of the manufacturing area and all analytical laboratories.
During the inspection, the 4
inspectors observed criticality and radiological control postings to insure compliance with applicable regulations and inspected several of the criticality areas to verify that the U235 holdings did not exceed the posted criticality limits.
No discrepancies were noted.
During the period February 26-28, members of IAEA (International Atomic Energy Agency) and NRC Headquarters accompanied the inspectors during their inspection to become familiar with NRC material control inspection procedures so that they could plan future inspections at licensee facilities within the United States.

On February 1, 1980, Region I was informed by the licensee that the physical inventory which was taken on December 13; 1979 could not be reconciled because of a number of problems.
The licensee also stated that he planned to perform a reinventory.
An immediate action letter (IAL 80-02) dated February 4, 1980 was sent to the licensee which stated that our understanding of actions to be undertaken were:
1.
Immediately begin preparations for a complete reinventory of i
2.
Initiate this reinventory no later than February 22, 1980.
3.
Provide the results of this reinventory to Region I office within 30 days after the start of the inventory.
The licensee attributed the failure to complete the December physical inventory as due to the failure of their data processing equipment to correctly reproduce data associated with fuel rods in that a card reproducer did not accurately reproduce the fuel rod weight and also could not handle the change of a 3 digit lot identification to a 6 digit lot identification.
Also, the new employees who were processing the inventory data weren't aware that erroneous data was being generated by the card reproducer.
The licensee could not retrieve the preliminary inventory data and chose to perform a complete reinventory of the entire facility.
The reinventory was taken on February 22, 1980.
The taking of this inventory was not observed by the inspectors, however, tests were perfomed of the accuracy of the inventory listing and of the licensee's adherence to procedures.
The inspectors reviewed the physical inventory data sheets and noted that each of the 363 sheets were signed by two individuals as support that the inventory was taken by teams.
Items which required sampling and assay to determine their SNM content, such as sludges, sweepings and residues, were selected from the listing and it was observed that these were sampled and the samples were being scheduled for Uranium and isotopic analyses.
Fourteen (14) items of the 24 hard scrap and oxidized / reduced powder items were checkweighed and there were no significant differen::e noted between the inventory weights and the checkweights.
Trays of rods and fuel bundles which appeared on the inventory sheets were traced to the location which appeared on the inventory sheets.
In some cases the rod count within the trays did not agree with the inventory count, however, these differences, were explained as being due to the movement of rods since the physical inventory.
Major items listed within each of the laboratories were selected for observation.
These items were either observed or shown to be in process.
The inspectors found no errors in checking the licensee's records of the control of inventory stickers and sheets which provide for assurance that all items are inventoried and no item is duplicated.
